3. LMH SERIES OPERATION
Power On
3.1 Leveling
1: Remove the LaserMark
®
LMH from its case. The unit is shipped with a battery current protection insert, which must be removed before operation. The unit can stand alone on a level, sturdy surface or be secured to a
5
⁄8" -11 surveyor’s tripod.
2: Press the Power button once, and allow time (up to 60 seconds) for the unit to self­level. The Power On LED (Fig. 1) and the laser will blink during this process. Please note, the laser head may begin to rotate before leveling is complete. The
self-leveling speed is approximately 1° per 4 seconds.
3: After self-leveling, the laser head will rotate at 600 RPM (LMH600 will rotate at the last selected speed. Press the Power button again to turn the unit off. (Note: for LMH-GR and LMH600 models, see section
4.3.2 (page 11)
(if blinking, unit is self-leveling)
LMH

LMH Series Rotary Lasers • 9
3.2 Re-leveling
If the unit is bumped or moved, the unit will automatically attempt to re-level itself. The Power On LED and the laser will blink during this process until the unit is level once again. The laser head will resume rotation.
LMH
X—AXIS ERROR
Y—AXIS ERROR
On the job site, it may be necessary to prevent re-leveling in order to prevent
SPINDLE ERROR
inaccurate measurements by the opera­tor. The LMH’s Anti-Drift System (Section
3.3) is used for this purpose.
LMH600
3.2.1 Axis Drive Error
If the LMH is set up or tipped beyond its self-leveling range of ±5°, the laser head will initially attempt to level; however, when the self-leveling limit is reached, the LEDs will blink, indicating an axis drive error (Fig. 2). Turn the LMH off, move the unit into a more level position, then turn the unit on again.
3.3 Anti-Drift System (ADS) (LMH, LMH-C, and LMH-GR only) By default the ADS feature is ON. The default setting of the ADS func­tion may be set to ON or OFF. When the unit is OFF, press and hold the MANUAL MODE (for LMH-GR, DOWN ARROW button) and then press the POWER button. Once the unit is on, turn the unit off for 15 Sec and then back on. ADS will not be the default when unit is turned ON. To make the unit return to ADS as default, repeat these instructions. When the LMH Series laser is fi rst turned ON, the ADS feature does not begin recording for 1 minute. This allows the instrument to be set up and adjusted. If after 1 minute, the unit is disturbed and the ADS light is fl ashing it is necessary to check any bench marks that have been made and ensure the proper "HI" (Height of Instrument). After the fl ashing ADS has been reset, by pressing the ADS button one time, you will have an additional minute to set and check your measurements. To turn ADS off press the ADS button once. This will put the unit into normal Auto
Self-Leveling mode.

3.4 Grade Mode: Single Axis Grade (LMH-GR and LMH600 Only)
The single grade function is ideal for general site grading, checking excavations, landscaping and drainage, and more. Manual grade mode can be activated by
Y-Axis
placing the automatic leveling sensor in the OFF position. Pressing the manual grade button will deactivate the sensor.
For greater accuracy in grade applica­tions, precisely level the laser level before entering into GRADE MODE.
LMH-GR LMH600
The selected grade can be as much as a positive or negative 10%, and set in reference to the Y-axis of the unit.
NOTE: The total percent grade possible is from a perfectly level base position. If the unit is mount-
ed on a tripod head which is not perfectly level, then the grade percentage range capable would be reduced by the slope of the base, as this affects the tilt range of the laser head. For maximum grade range, ensure a level tripod head using a spirit level before mounting your unit.
Operator can use one of two methods to generate single-axis grade (Fig. 4). Method 1: Place

6. LMH SERIES CALIBRATION
Your LaserMark® level is a sealed unit and is calibrated to precise accuracies at the factory. However, a calibration check is recommended before the initial use of your laser, and then periodically from that point forward. Be sure to allow time (up to 30 seconds) for the unit to completely self-level before each check.
Please note the direction of the X and Y axes for the unit (Fig. 9). You will need to refer to this to complete the following steps.
6.1 Upright Position Peg Test (X axis)
®
1: To test the X axis, mount the LaserMark
on a tripod or a level, sturdy surface and place approximately 100 feet (30m) away from a wall. Face the left side of the unit (X- quadrant) to the wall.

9. TROUBLESHOOTING
The following information lists basic tests that can be performed to check the LMH in the event of poor performance.
Check Your Batteries: One of the most common causes of perfor­mance failures is due to defective or incorrectly installed batteries. Check to see if any batteries are installed backwards and correct if necessary.
• Never selectively replace batteries; always replace all of the batteries at the same time with new batteries. It is recommended, if possible, that the batteries be checked with a voltmeter or battery tester to confi rm proper voltage.
• Leaky batteries may have damaged the battery contacts in the battery box.
• Check to see that the battery tray is screwed tightly onto the base of the unit. Also, the fi t between the battery prongs and the batteries may need adjustment, as this fi t may vary over different brands of battery (especially Energizer™ brand, as they are larger in diameter, preventing a proper connection).
• Alkaline batteries are recommended for the best performance and storage life. Rechargeable batteries such as Nickel-Cadmium will provide performance, but are not as desirable due to their lower terminal voltage. Low cost standard Carbon-Zinc batteries may be used in emergencies, but they should be replaced with alkaline batteries when available.
Rechargeable Battery Pack: For maximum battery life, the battery pack must contain a full charge. The batteries will begin to perform optimally after fi ve full charges and discharges.
Unit does not rotate or self-level, or produces Axis Drive Er­ror: Reset the internal processor by turning power off and on again.
You may also try removing the battery tray for 15 seconds to let the capacitor discharge, then replace the tray and try again.
If the unit rotates but does not self-level, be sure that the Anti-Drift System is turned off.

upward and downward direction until the LCD beam indicator arrows appear and/or a pulsing audio signal is heard. Use the Beam Resolution feature to choose between the coarse/low setting, used for approximating level or for initial locating of the center level point, the medium setting, used for greater accuracy, and the fi ne/high setting, used for the most accurate pinpointing of level.
4: Move the detector upward when the low beam indicator light is lit (with volume on, a short pulsing audio tone is heard). Move the detector downward when the high beam indicator arrow is lit (with volume on, a long pulsing audio tone is heard). When the beam is level, the level beam indicator line will be lit and a solid audio tone will be heard.
If the detector is not struck by a laser beam after 5-8 minutes, the detector will automatically shut itself off to preserve battery life. Turn the unit back on using the power button.
28 • LMH Series Rotary Lasers
5. SPECIAL FEATURES
This detector has a unique memory feature, which preserves the last position of the laser beam if the detector is moved out of the plane of laser light, as well as built in electronic fi ltering for bright sunlight and electromagnetic interference. Three distinct audio tones (high, on-grade, and low) assist targeting from a distance.
Features speaker Off, Loud (105 dBA) and Louder (125+ dBA), fi ne, medium, and coarse beam resolution settings, and front and back LCD displays. Seven distinct channels of information (Fig. 2) indicate the position of the detector in the plane of laser light. As you move the detector closer to the center, the arrows fi ll in to indicate the laser position.
